Making money in the market is not as easy as some make it sound. I started back in 1969 and never had much success until I retired in 2015 and could devote full time to this "hobby" or "job" depending on how you look at it. Since that time I've more than tripled my portfolio. Granted I had some luck on my side with a few big winners, but as long as you manage your losses well, then really all you need is a couple of big winners per year. Its all up to you how much time you can devote to this and reading 1 or 2 good books can help as well. Lately, I have found that following the "right" people on IHub that have great stock picking records can be extremely helpful as well.
Good luck to you.
P.S. SIGO is probably not your best choice for cutting your teeth on. This stock is extremely volatile (just look at the one-year chart) and would be difficult to trade, even for an experienced trader (in my opinion). It could be a good choice to buy and hold (although I wouldn't recommend that to a newcomer) since the marijuana business in California could be a tremendous revenue generator for those entities that are large enough and experienced enough to take advantage of this, perhaps, once in a lifetime opportunity regarding marijuana legalization in California.
