Author argues Acorn Energy is a cheap, debt-free microcap with downside protection from its P/S ratio and 2-3x upside as a growing monitoring business.
ACFN — LONG The author argues Acorn Energy, a $50M microcap providing monitoring devices and services to energy generators, is undervalued with a P/E of 7, P/S of 4, no debt, and a CEO owning 20%. The author uses the P/S ratio as downside protection, noting software companies typically sell for a P/S of 6 in private equity markets, implying at least 50% upside, with more potential given growth. The author states they own just over 0.1% of outstanding shares, about 7% of their portfolio, and sees 2-3x upside potential.
Just based on the P/S of 4, this company offers at least 50% upside. Software companies usually sell for a P/S of 6 in the Private Equity market. But I think this is more than a 50% upside play because they are a growing company.
