52-Week High Momentum

52-Week High Momentum is a position-trading momentum strategy with strong academic backing: it buys stocks printing new 52-week highs and rides them, exiting only when the trend breaks below its 50-day moving average. The premise - well documented in the momentum literature (George & Hwang's "52-week high" effect) - is that stocks near their yearly highs tend to keep outperforming, because the yearly high acts as a psychological anchor the market is slow to re-rate through.

It is an easy, momentum/trending, daily strategy.

How it trades

Buy (new yearly high):

Close >= HIGH52W()

Sell (trend breaks):

Close < SMA(50)

HIGH52W() is the highest high of the prior 252 bars (the current bar excluded), so Close >= HIGH52W() reads as "today's close reached or exceeded the past year's high" - i.e. a new 52-week high. It takes no arguments: the window is fixed at one trading year.

The asymmetry is deliberate: entry demands a strict new high (a rare, decisive event), while the exit is a looser trend-following stop (a close below the 50-day average). The strategy enters hard and holds loose, letting winners run for months.

When it works best

A position-trading tool with strong academic evidence behind it, best on names in durable, multi- month-to-multi-year advances that repeatedly make new highs. Its documented weakness is that it can buy near tops: a "new 52-week high" is sometimes the final blow-off, and because the exit only triggers on a close below the 50-day average, a sharp reversal from a high can give back a meaningful part of the move before the strategy is out.
