As the title says this is my 2nd week of day trading, I put about 20-25 hours in my first week and made $1535 the goal is to make at least $1000-$1500 a week for 6 months and I will continue to day trade if I can make $1500-$2000 a week I will quit my day job and fully focus on this.
My method/strategy is simple, I wake up about an hour before market open and check the news, get ready for the day, and get some charts up. I have a 5 screen set up that I use to trade where I normally run up to 11 charts at a time, I look for trending stocks that have some momentum to them and volume and I scalp the peaks and valleys, I don’t trade stocks that I wouldn’t invest in, and I try to stay away from the biggest of companies.
I have 4-5 years experience in stocks and figured I could take \\\~$50,000 to day trade with here are my results so far.

A lot of this I suspect is driven by retail. Pull out a few high beta stocks like AMPX, POET, INFQ, as an example: these have ran almost 50% over the past few weeks.

CVV designs, develops, manufactures, and sells specialized process equipment — primarily chemical vapor deposition (CVD), physical vapor transport (PVT), thermal processing systems, and ultra-high purity gas/chemical delivery control systems.

Equipment for producing nanomaterials used in batteries — directly supports next-gen battery tech (e.g., silicon anodes or advanced cathodes that companies like AMPX might leverage).

Silicon carbide (SiC) and gallium nitride (GaN) — critical for efficient power systems in robotics, EVs, and industrial automation.

Semiconductors, LEDs, carbon nanotubes, nanowires, solar cells, and general industrial/research applications.
A very similar story to POET and TRT, feels like a great way to get involved in the sector. Feel free to add any thoughts.

The below are bag holders lol, try look at actual companies. SYM (robotic warehousing), VPG for sensors, OUST for lidar, Teradyne is good, AMPX for batteries. Many more... Amazon will also be involved. Rokwell... Japanese companies like FANUC... RR and stuff is just a gamble.
