Is FINRA supposed to echo the SEC rules? One would think. DId FINRA make a mistake in 2017 and not follow the SEC rule for stock (non-cash) dividends? Possibly.
Frankly I'm happy the pps didn't really slide much yesterday. Perhaps people aren't caring so much about the dividend this time - they care more for the underlying stock and aren't selling.
