I'm not sure how much an economics degree would even help in investing. I studied economics as part of my degree, and I can't really say it helps me much in the market. It's good to understand the theories, but even top economists are pretty bullshit. None of them saw the 2008 financial crisis until it was too late. Only the Austrian economists/some libertarians saw it, and they didn't teach that in university. With trading, timing is key. Investing in a shit stock with good timing will yield returns. Investing in a great stock with bad timing won't.
Banking, telecom and technology is what I like. I liked gold too, but the price of gold and how easily it's manipulated by paper contracts is something I don't like.
Just take the rich guy's stock - Berkshire.
I got economic degree and i can tell you its bullshit, all they teach there is stupid Keynesian money counterfeiting based economy, and a bit of classical Smith economy, still not sure how they can teach both of these 2 simulatenously when they contradict eachother.
Yes investing requires timing too, but if you are in for the long term picture, not like a short term speculator, then just pick the right stocks and wait.
I think gold stocks have potential, the manipulation is the reason why, because gold price is now held artificially low, it can go only higher than tat, although it would not invest in Gold mining sector , but rather vaults or coinery type companies, or those who melt gold bars, but only those which are located in safe countries, preferably in the Chinese influence zone.
Although I decided a while ago not to invest in the stock market anymore for obvious reasons, if i would, then i would do those i said in the previous posts.
