The SEC has ruled that Sunpower Class B shares can not be converted into Class A shares for 2-years. This is part of the tax-free CY distribution.

SPWRV has 8:1 voting advantages. You can have the preferred share (Class B: SPWRV) vs. the SPWR (Class A).

If you hold SPWR right now, the only advantage is to wait for a short squeeze. On the morning of Sept 30, however, the CY distribution of SPWRV shares will occur.

Any SPWR (Class A) shareholder right now who doesn't sell SPWR and buy SPWRV hasn't read the SEC filings; analyst reports on the spin off implications; or doesn't care about making an elementary trade to benefit their financial well being.
