Investing is little more than a fancy word for gambling. Borrowing money to gamble is a bad idea. You don't want to find yourself here in a few weeks asking for a loan to "win it all back". Remember only speculate with what you can loose.
For people who didn't make their homework, yes, it is gambling.
For people who do their homework, it is never a gamble.
If you put money in a company knowing that they have a good product, you confirmed that their management is experienced, and checked that their sales team is sharper than a knife, then why on earth it would be a gamble? You project their potential earnings and weight them out with their the potential risks.
If you put money in this case, it is investing.
If you put money in a company you know nothing about, you don't know about their business model, don't know who they are or how experienced they are in whatever they claim to do. You don't know how much money your investment will make, and what are the potential risks.
Then that is plain suicide.
If you put money on it, certainly it will be a gamble. A stupid gamble.
And yes, if you put money based on Technical Analysis, it is also a stupid gamble.
