I've also heard of it referred to as 'trying to catch a falling knife'. Especially when purchasing highly speculative and very risky stock such as SWET, with no guarantee or return on investment at all. That's why its high risk, with a slim chance of high reward.
But so is drinking and smoking. People still do it, the same way they preach and spout off incessantly and redundantly and expect it to be heard as gospel. There is no reward, without taking a risk. And that's what investing in SWET is, a big risk, but one I personally feel is worth taking and investing in.
