Have had my eyes on SYA for a couple of weeks (or is it 3 wks?) now, since diabolical commies cut off graphite to the Western world. So, been monitoring SYA and TON, but ended up buying neither. But your mentioning SYA piqued my interest once again, and share price chart shows on 27th Jan '23, s/p was 28 cents, and yesterday it was 8.1 cents? Wow. S/p worth less than one-third what it was 10 months ago. Surely with diabolical commies halting exports, this company should be seeing its s/p go through the roof? What am I missing? Tempted to buy a small number, say 10000, on Monday, but that'd cost me around AUD 900 with broker commission, and I don't want to lose even that small amount if this company turns out to be a complete dud. There's a reason why s/p has depreciated 3.5 times since January. Just don't know if I should take a position.
