I don't think this is diversification: To make things worse, 7 of the top 10 are in banking/finance. Sounded like he preached one thing and did just the opposite.
Also set your stop loss far far away. Do not panic and tighten your stop too soon. Give allowance for market to retrace / pull back.
Most important of all, do not listen to the experts blindly. Do not listen to our golden rules blindly. Trade plans, golden rules are not transferrable. You have to develop your own holy grails, trade plans & golden rules.
I actually agree with you sir. After been stopped out of my FB @ $20 (after IPO), AAPL @ ($400 prior to split) because I read O'Neil and put on a 8% stop. Couldn't get back in on both until recently. Where were you when I needed you?
millions of experts said keep your stops small. But my trade plan says keep my stops big. well. cannot blindly listen to the experts. Those experts failed to quantify how small the stops should be. also they failed to realise different people have different experiences, and different programs in our subconscious mind.
