My experience as a stock trend trader.
If trading small size, this allows for a greater number of opportunities and allows to grab more opportunities because of time. In other words, as time moves on you have more balls in play.
This only works if you are very careful in selecting high probabilities. High probability being the market is bullish, the stock according to your criteria is the pick of a bunch, carefully screened.
With time, holding a large portfolio of small sizes, it's easier to stay in the trade for longer because each individual risk is smaller.
The markets over the years keep rising, the bias is upward, you can't profit from this if you are not in.
Jumping in and out becomes tiresome, most stocks require time to work out.
On drawdowns, these become opportunities to add to positions, not exiting on drawdowns but entering with incremental small positions.
