Why won’t Porinju Veliyath sell these stocks with over 45% decline & falling profits

An ace Investor followed by many, Porinju Veliyath is probably swimming against the tide with two of his favourite holdings. He is still holding two lesser-known small-cap companies that have seen a big fall in sales and profits, along with over a 45% decline in share prices. Is this a warning bell or a blessing in disguise?
