Looking at the history of a company to predict the future,...

Looking at the history of a company to predict the future, without bothering to understand why each of the points are hit make it like a horoscope. Sure, the chart doesn't lie, but it also doesn't tell you anything about the future. It doesn't tell you if tomorrow the company goes into administration. That would certainly deprecate any trend that might be forming. And by just changing a couple of small points, you come out with a different result. There are no error bars on the chart that was shown. You guys might be expert chartists, but you are certainly not scientists. Do you even have a tally of predictions right/wrong? Have you ever studied mathematics above a high school level? If this is the way you want to trade, then fine, but don't try to sell it to me, especially in such a turbulent environment.

Another thing, the chart is of course going to stop dropping in magnitude. It can't go lower than 0, and when you shown the chart on a linear scale going as high as 30 or more, it is going to look like it has bottomed out.

0 is the asymptote. If you viewed the y axis on a logarithmic scale, you'd probably see a linear drop that is continuing, within the error bars.
