I feel at home on the long side - my short operations lose nearly all the time.
When I stopped shorting my P&L skyrocketed.
It use to bother me that I wasn’t a ‘real trader’ if I couldn’t take both sides - but that’s dumb there are many long only or short only traders - and the real proof of a trader is profits not market direction.
With all that said I do still worry when we have big stock market sell offs (my best trades tend to be stock CFDs).
The only way I get hedge that is by trading gold, a few currency pairs, and recently started trading the VIX.
Also not all the stocks I follow go down at the same time thankfully.
I would definitely recommend that beginners have a bias for one side of the market (it needn’t matter which)…
Simply because we can focus our attention that much better on one side.
