LT Gain 300 differs from LT Gain in two ways, not one, and the second is easy to miss:

  1. During the recovery phase of a U.S. equity drawdown, the equity position is held through a 3x S&P 500 ETF (UPRO) instead of an unleveraged one.
  2. In the first month of a defensive run, the Risk Off position is TMF, a 3x long Treasury fund, instead of the unleveraged EDV that the base strategy and LT Gain 200 hold.

Everything else is identical. Same momentum measure, same Risk On / Risk Off test, same Treasury Duration Limiter ladder from month two onward.

LT Gain 300 is one of only two strategies in the DMS lineup that applies leverage to its defensive position, the other being Global Navigator 300. It is also the most concentrated leveraged strategy on the site: a single market, a single position, tripled.

What the 300 means

LT Gain holds one ETF at 100%, every month, without exception. Substituting a 3x fund for the equity position triples the portfolio's notional exposure to 300%.

There is no sleeve structure to dilute that. Triad 170 leverages a 35% sleeve and reaches 170% notional. LT Gain 300 leverages the only thing it owns, so when leverage is deployed the entire portfolio is a 3x S&P 500 position.

How Smart Leverage decides

The equity module is identical to the one LT Gain 200 uses. Only the fund differs.

Dormant. Nothing happens. LT Gain 300 holds exactly what LT Gain holds.

Armed. U.S. large cap has closed a month 10% or more below its highest prior month-end close. Arming and deploying cannot happen in the same month.

Deployed. Leverage deploys in the first month where U.S. large cap's momentum has turned back up and the strategy is Risk On. Smart Leverage cannot override the Risk On test, so a 3x position is never held into a decline the base strategy had already exited.

The three exits

  • Momentum turns. T-bills catch up to or pass U.S. large cap on the weighted-average measure.
  • Any Risk Off month. The strategy leaves equities and the leveraged position goes with it.
  • The 13-month cap. No deployment runs longer than 13 consecutive months.

The cap matters more at 3x. A leveraged fund tracks a daily multiple of its index, so its return over a long holding period depends on the path the index took, not only where it ended. Choppy, high-volatility markets erode a 3x position faster than a 2x one, and the effect compounds with time held. Capping every deployment at 13 months bounds that exposure by construction. The figure is 13 rather than 12 so a full-length deployment clears the one-year holding period for long-term capital gains treatment.

One trigger, one deployment

When a deployment ends, for any reason, the drawdown that armed it is spent. Only a fresh 10% drawdown from a new peak can arm it again. At 3x, that restraint is the difference between an overlay and a liability.

There is no "Prolonging the Magic" rule here. LT Gain has no second equity candidate to rotate into, so the exits above are the complete list.

The leveraged defensive month

This is the part that deserves the most attention, because a reader who skims will assume the defensive position is the safe part.

When the strategy goes Risk Off, the Treasury Duration Limiter picks what to retreat into. If long Treasuries are still trending positively, the first month of a defensive run holds a long-duration position: EDV for the base strategy and for LT Gain 200, and TMF, a 3x long Treasury fund, for LT Gain 300. From month two onward all three variants hold unleveraged TLT, and once the Duration Limiter fires, all three lock into short-duration BOXX for the remainder of the run.

So the leveraged defensive exposure is bounded: one month, and only when the Duration Limiter has not already fired. But within that month the portfolio holds three times the duration risk of the base strategy, at precisely the moment it has just decided equities are unsafe.

The case for it is that the first month of a defensive run is when a growth scare is most likely to produce a sharp Treasury rally, and the Duration Limiter's sign test is what keeps it from happening during a rate shock. The case against it is that the sign test is backward-looking, and a month in which long Treasuries reverse hard is a month in which a 3x Treasury fund reverses three times as hard. Both are true.

It also means LT Gain 300 can hold a leveraged position in consecutive months for opposite reasons: a 3x equity fund while Risk On, then a 3x Treasury fund the month the signal flips. Understand that before choosing this variant.

What 3x costs

January 1980 through September 2026, net of trading friction:

CAGRMax DrawdownMAR
LT Gain+12.7%-23.4%0.54
LT Gain 200+16.0%-24.1%0.66
LT Gain 300+20.4%-31.9%0.64
S&P 500+12.0%-51.0%0.24

Read the MAR column, not the CAGR column.

The first doubling of leverage is the efficient one: more return for a modest deepening of drawdown, and MAR improves. The second doubling buys a further step up in return and pays for most or all of it in drawdown depth, with MAR flat to lower. The pattern is the same one the Catalyst family shows, and it is what you should expect: the marginal unit of leverage costs more than the one before it.

Note also that LT Gain 300's maximum drawdown is the deepest in the family by a wide margin, and that this is a single-market strategy. There is no second sleeve to cushion it.

Undiversified, and now tripled

LT Gain's entire return stream is U.S. large cap or Treasuries. It is a concentrated single-market bet with a trend-following exit, not a diversified portfolio. LT Gain 300 takes that and triples it. There are stretches where the whole portfolio is one 3x fund tracking one index.

Who it is for

LT Gain 300 suits an investor who already holds and understands base LT Gain, is comfortable with the entire portfolio being a single leveraged fund for months at a time, has a long horizon, and has thought concretely about their own behavior during a drawdown rather than assuming they will be fine.

It is a poor fit if any of the following are true. You would not hold base LT Gain on its own merits. You have not held a leveraged position through a drawdown before. You are uncomfortable with a leveraged Treasury position in the first defensive month. You want risk to come off in stages rather than all at once. You are investing in a taxable account and are sensitive to short-term gains. Or you are drawn to the headline return without having read the MAR column beside it.

LT Gain 200 runs the same equity module at 2x, holds an unleveraged defensive position throughout, and for most investors who want leverage on this strategy is the better starting point.

The base strategy in brief

LT Gain asks one question each month: is U.S. large cap beating cash on a weighted average of trailing 1, 3 and 6 month returns. If yes, it holds U.S. large cap at 100%. If no, it steps out entirely and the Treasury Duration Limiter decides what kind of safety to hold, stepping down to short duration when long Treasuries are themselves losing money and locking that choice for the rest of the defensive run.

Past performance, including backtested results, is not indicative of future results. Backtested performance is hypothetical, does not reflect actual trading, and benefits from hindsight in the selection of strategy rules. Portions of the long-term history rely on reconstructed proxy data for funds that did not exist for the full period. Leveraged ETFs carry risks beyond those of their unleveraged counterparts, including the effect of daily rebalancing on returns over holding periods longer than one day. A 3x fund can lose value over an extended holding period even when its underlying index is flat, and this applies to leveraged Treasury funds as well as leveraged equity funds. Investors should carefully consider their risk tolerance and consult with a financial advisor.
