I do have some investments
I am a beginner, though, and I try to diversify my portfolio. Perhaps a thread with suggestions would benefit all of us
While I am likely speaking to a spammer (one does not tend to bump a year old thread as a first post)
Legally that gets tricky, even with the "not investment advice" disclaimer.
Practically it is even more tricky -- as a general rule investment firms rarely beat the index, and those that do rarely manage it for more than a few years on the trot. Chances of randoms on a forum being able to do it then being seen as even less than that.
Or if you prefer.
Peleton. The exercise bike company. They slapped a tablet on an exercise bike, sold a subscription video service with it and somehow got valued like a tech company, this despite there being a million exercise bikes stuffed in the back of sheds all over the developed world and getting sold on like the proverbial village bicycle whenever there is a yard sale/jumble sale/car boot sale/... with nothing to stop another company/youtube channel from taking their business. For some they were on these pandemic stocks that rose massively on the back of "stay in your home citizen".
Their price tanked the other day; was it because they have masses of unsold stock and no real prospects for growth? While it is true that they are not selling anything then no. Did them being valued like a tech company that can sell a billion copies about as easily as a million with most of that being pure profit despite being a widget maker catch up to them? Sadly not the markets are still rather irrational in that regard. Did a character (said character being an unhealthy type) on a TV show die and just so happen to be on one in that scene? Yes, tanked as a result with the medic for the company even having to make a statement to that effect. Since then rumours (not actual hard date, rumours) of a buyout saw it creep back up.
There are a million other companies all over the world, all interrelated to each other in various ways or representing market segments that are related with 1000 potential news events a minute to change their valuations dramatically.
Can a hacker style approach to data and tech help? Yes actually, though in reality many have already gone there (Wall street being one of the bigger employers of high end computer science students) so you face an uphill struggle. Though also as noted above then investment firms with billions to spend often fail to beat index funds (buy one of every stock on an exchange, congratulations you are done) so chances of you doing anything are less likely still.
