Its all fundamentals. Quarterly reports, earnings, and how well a company is run, yet most importantly how it does in relation to the market and world affairs if it applies. I hardly ever buy what the experts recommend, since in my opinion they are simply peddling their own portfolios. Its really a trial and error experience, over time, you simply become more efficient with your profits as you minimize your mistakes and thus lowering your losses.
what's been happenning with NFLX? i was going to buy it few months back, but now i'm glad i didn't. Although it would have been nice to buy it 2 years ago.
