I disagree with your assessment about not knowing a bad vs good company. By the very nature of your comments I know you shouldn't be investing in Stocks. If you were a savvy investor and understood their business model and cost structure (Financials, BS, Cashflow, competitive advantage,) you would know all those companies (nortel, air canada, GM etc)were going down the toilet. It's all about research and sticking to industries you understand. If you can't do this on your own then stay away from stocks. I do my own research and trust nobody. Before I invest in a particular stock I spend 3 months of effort researching and analysis (history, Listening to Quarterly calls, 10K, Competitors, Historical and projected Financials, Management Integrity and honesty, Business Model, Speaking to friends/Contacts in the industry, Industry Drivers and Forces, Strategic competitive advantage, Business Risks, Intrinsic Valuation etc) How much do you? If you don't put this type of effort of research then you are just gambling and throwing your money away. Generally avg joe spends more time researching a purchase for the latest greatest electronics/car than their own investments.
"I think it's too much of an gamble right now. Who would have thought that GM would tank? This is a company that traded at 25.64 an year ago, it traded at 1.80 today and can be compared with Nortel, 360 Networks or Air Canada all of which rewarded their equity share holders with 0 value as they went bankrupt.
It's impossible to know which companies have run out of operating credit until they have, it's impossible to know which companies have been over leveraged until they file for bankruptcy.
In the case of Nortel and 360 Networks, the financial industry kept trying to get people to buy the shares right until the regulators closed the market in their shares.
Right now, it's impossible to know how many suppliers to GM and Chrysler will die despite contracts with other manufacturers and the auto parts industry. In fact, some of the suppliers to GM and Chrysler aren't immediately apparent to the person who isn't an industry insider.
Then, there is the effect of the US Depression on the Oil Sands in Alberta, the Lumber Industry in BC, the Steel Industry in Ontario and even the electric energy suppliers in Newfoundland, Quebec, Ontario and BC.
How much electricity are we transmitting to the US right now that will never be paid for? Are we going to see States like California declare that they don't have to pay the bill the way they did in the 1990s?
It would be a full time job keeping track of all this stuff and I already have a full time job."
