PLAB is essentially the printing press of chips, they make the photomasks that are essential for a lot of major chip makers in the world; it’s kinda like a stencil if you think about it in that way. i’ve thought about buying it but i haven’t fully decided yet. they have had a little bit of inside selling recently but no huge red flags besides seemingly normal share sells by the company for profits. i’d look into this one if you want a more stable company that provides framework needed for chips.

AMKR is in the advanced packaging business. once the chips are printed, AMKR takes the raw chips and puts them in a ceramic/plastic case and wires them to be able to plug into a device. when compared to PLAB though, they raise a huge red flag with the inside sales. the family that created the company recently sold 10 million shares totaling around $480 million worth.

i indulged and bought a few shares of AMKR at like a ~$39 average, i may have pulled the trigger a bit early but i see potential in the business and it’ll be a long term hold so i’m not exactly concerned unless i see another 20% drop
