Poor stock picks

I have been totally unimpressed with your stock picks over the last several months. Long winded analysis leading to total flops. Perion, Occidental Petroleum , Boil have all been losers. You recommend not to buy Nvidia when it was in the mid- low 100’s per share, and to wait until it dropped to a $100 per share and $50 per share.It has become the darling of Wall Street. I am now hesitant to purchase any of your picks and will likely cancel my subscription when it is time for renewal. SDavidoff
