Give yourself some purpose to your trading. Making money, having an extra stream of income, having an extra stream of excitement, having an extra stream of risk to manage, having too much streams of money...you can be more creative than me, come on, there has to be a purpose to your trading. Maybe it is to support an ethical company, but do get real. Investors talk about ethics in investing. Yea sure, as if the ethical company needs your money no matter how small. Love yourself first, then you can better love an ethical company. So invest/trade/gamble whatever suits you for your own wellbeing. The ethical company will not take care of you that well. Financially yes sometimes (but rare, and what if they are lying), but do they also care for your personal health, wealth and peace of mind? So there, that is why thousands of investment/trading books say 'do not say I love you to the stock' and 'do not say I want to marry that stock'.
Okay, so we got that point settled. Now I can more easily say go long and short your stocks. Is shorting unethical? (Meaning you sell first then you buy back later. Google it, that is what it is for). You want to make money out of your due diligence in analysis and research in your stocks. You believe by doing that, you can ensure that you make money from the market. No, no I do not think so. Lots of hard working people do that. 95% failed. Hard work in this sense has no basis for success in the markets. Think you are smarter than 95% of the market? IQ has also no basis for success in the markets. Why? The market and stock price movement has no rules other than what the collective consciousness in the market determines. Why? The collective consciousness ruling the markets on Earth are largely human in nature. Spock, my Vulcan friend said so. He also said in the planet Vulcan, markets are orderly and rational, and all prices are fixed because all the potential of the company has already been factored into the price. The stock price stays the same for decades. So there is hardly any excitement and profit in the markets. Prices go as predicted by the masses and hence no one is selling a good stock. 95% of Vulcan traders are just waiting for decades to buy from the 5% of Vulcan traders who went bonkers and decide to sell their good stock. And they buy good stocks and shun bad stocks. As a result bad companies are simply bad and Vulcan CEOs delist their bad company almost immediately upon listing and close down soon after. Spock simply do not understand the markets on Earth. Earthlings are simply irrational and incorrigible. Spock says he will go mad trying to trade the markets on Earth.
So ethics do not a good company's stock make. Of course there is some fundamental truth in fundamentals fundamentally telling the fundamental direction of the stock price. But these are more long term. And in the short span of 1-2 years, irrational behaviour rules, because it is just human nature. Meanwhile the fundamentals do change. Not to mention, all company reports always try their earnest best to look hansome or beautiful or simply just appearing earnest.
So I do both long and short positions. But always with the clear trend. If the chart is obviously trending up, I go long. Trending down, I go for short positions. Sideways? Then I look for a bigger picture until it is either clearly trending up or trending down. Will banning shorts reduce the uncertainty in the markets? No. The human element always comes in to introduce more complexity in one form or another and hence uncertainty. Is it unethical to profit from a short position? How about a long position? In the end is making money unethical? Not if the company is ethical?
Therein lies the importance of knowing your purpose of trading or investing. Know thyself, know what you want from the market, be real. 'It is costly to find out who you are in the market'.
