Your logic is flawed. Of course a stock can go up w/out a dividend, but to say a dividend doesn't provide some price support is just absurd. High yielding dividends increase share demand and reduce downside price risk. For you to not understand this basic concept tells me you indeed are a fool.
You asked how long I've been an investor: I began trading in 1983. I've had good and better years and have never endured a lengthy losing streak, unlike you with your banking and housing stocks.
