Splits have no effect whatsoever on the value of ones shares. The SP adjusts to compensate for the reduction or increase in dilution.
The reason that changes in the split adjusted SP often take place afterwards is because of the reasons/factors that led to the split and not to the split itsslf. An example we've just seen is the reverse split after NNVC's recent split{ because it was for the purpose of moving to a higher exchange, a move with strongly positive implications, there was a very positive effect on the split adjusted share price.
Reverse slits can be either highly positive (when for a move to a higher exchange) or highly negative (the SP is so low (usually because of greatly excessive dilution) that it's in sub fractions of a penny).
Generally forward splits are done when the SP gets well above $100. The reason is that most buy shares in multiples of 100 and when the SP gets north of $100, a lot of 100 shares is more than many investors can afford or want to put into one company. (there's no rule against smaller lots of shares and I did it many times when starting out with peanuts. The trades are slower to execute and get worse prices and the commission is a much higher percentage of the sale, so it's not feasible for trading in and out)
Not every company does forward spilts: Berkshire Hathaway has never done a split and now trades at north of $174,000 per share.
There would be no point whatsoever in NNVC doing a forward split until the SP goes north of $100.
If you really don't like the odd numbered lots of shares that can result from a fractional split, the answer is to just sell or buy one odd lot to even it out (When is often done to even out a partial fill) Selling the ONE extra share that resulted from the rounding up after the 3.5 reverse spilt (I FINALLY got mine!) would LOSE money because the commission would be more than the sale. So the answer is to add or deduct that one share from your next sale or buy.
While a future forward split may well happend due to a growing SP, it would almost certainly be in one of the common ratios of whole numbers: 2:1, 3:1 , 4:1 etc. I've NEVER see a comany do a fractional FORWARD split
Fractional splits are often done on reverse splits to keep the reduction in number of shares as small as possible while still meeting the requirements of the exchange (with a reasonable buffer for volatility) simply because of the illogical reaction of some investors to "losing shares"
The number of shares of your holding is insignificant: what COUNTS is the fraction of the company your holdings represent. And that is totally unaffected by splits (although it may be affected by other things sometimes done in association with splits).
