This is where we want to focus on one or another selling point of the stock, share or currency to bank on. Honestly, typical brokers have as much understanding about 'worth' and 'appraisal' as a grade school kid in a wood working shop knows about engineering... there are so many aspects and angle to use in your private pitch that defies the mind! Honestly, this is great frontier, not just some board with numbers and risk analysis! The figures don't really matter, it is the grade and price of the products they sell, of course, and, knowing stuff about marketing would help no end in this. So, trading is all about technical, market, psychology an other angles combined.
of course this is a vibrant job to be in, and I encourage parents to sit with their kids and analyse the products with them. Think of a learning experience for them, not, "Oh that is junk," but rather, "Why is it junk, Jonny?" Think about breeding a middle man, a market savvy shopper?
Anyway, this thread is focused on this, the markets and the value of goods, currency and production and service companies.
