i wouldn't confuse investing with fucking around with penny stocks. does technical analysis actually mean anything or is it the herd of the crowd thinking it does and fulfilling their own prophecy? some guys who are good at it do have good records - notably tim sykes who will teach you how to do it. in the past he used to do mostly shorts and would also pore through filings to find shitty companies that were destined to failure. a tough part about some of these rinky dink stocks finding 1. a broker who will trade them and 2. shares to locate when you do want to short. if you want to get serious about trading like this, tim is a good guy to follow. i have one friend who day trades using something he came up with who has had a pretty good 18-24 month run. tim himself has gone from something like 1000 to 1m now, i think twice.
imho the market in general is overvalued because of quantitative easing. it's bullshit, but bullshit can keep going until it doesn't. now if you could time that, you could really come out ahead. harder than ever to do now though - because the .com bubble and housing bubble had plenty to do with real things and people they could be reasonably timed - now there is so much federal reserve intervention in the market, who knows.
tesla itself has benefit doubley so from QE, both from a stock/market perspective as well as creating wealth effects (the intention of QE) for those that are in its target buying demographic. since the housing bubble collapse you can see stocks have made a stock holding class whole; people on the top in today's economy are feeling good again. people on the bottom are still fucked. tesla itself as valued as a technology company, even though what it really is is a car company, and one dependent on the physics of battery chemistry, which does not progress anything like technology. imho big money to be made on them falling over if you have the timing right. i hope to be in on that.
if you want to be safe just stick money in ETFs and leave it alone. i think you can speculate some industries will do better than others and park cash there. don't do anything self guided unless it's with your fuck around money. i have made big gains and big losses with the fuck around stuff. lots of little ones too. what is really frustrating is if your theory is right but the timing is off. note these were on bigger things than the penny stocks which i consider dice rolls (or worse) until you are at least semi-competent, else you are merely competing with a tim sykes. my stuff has been more based on things like natural gas should rise because of x theory and making a bet on it. i bet largish and infrequently these days. my last 2 non-trivial investments were both private equity in companies, one is a buddy's and the other is a bit more established alcohol detection system; it detets it through your skin. projections and use are all for commercial workspace but it's possible the technology may find its way into the start/stop button of your future car. it can identify who is in the seat too so you could potentially program it to not start the car if it's not you, or send you a text message if your kid has been drinking or is above a 0.04, etc.
I tossed $5 in because I'm not going to cry if it busts, same entertainment value of a lotto ticket.
my coworker has told me to buy "real stock" and put upwards of 3k in... which knowing my luck I'd buy apple and it would drop to 50% of its current value.
lots of little things, after you get past the free trading, basically results in lots of fees you pay for your broker, plus annoyingly painful to do taxes. it is also kind of lame to put in the "time/work" and make... $10. what are you going to do, buy an extra burrito? time/tradeoff is much more valuable doing something like i have done with my blog, working banks and the credit card and points game. you can turn that into thousands of dollars worth of cash or travel. by now i think i might be able to charter my own jet at AA and i might be closing in on doing the same with united...
you should have more of a theory around just plopping some money into something. like you should have a theory of whether tesla is worth 50 bucks or 500 and decide from there if it's at 250 if you should buy. also a pain point to cut your losses and a sell point to take your profits. this is what someone disciplined would do, at least - i don't always practice what i preach. i have big volatile expensive bets in my account and i have stupidly not even really looked at them for 6 months. it will be an expensive day as most are losing but i think i'll log in now and push them out to the future some more and hope these theories eventually work out for me...
