Training melons and watermelons to grow vertically is referred to as trellising and is one of the advantages of growing melons in a high tunnel. Most melon cultivars and personal size (less than 7 pounds) watermelon cultivars are amenable to trellising.
A direct public offering (DPO), like the more traditional IPO, is a stock's introduction to the stock market. The stock is offered to the public for the first time. Unlike an IPO, which utilizes an underwriter to sell shares to the public, DPO shares are purchased directly from the issuing company.
Many IPO investors, at least those lucky enough to get in at a company's offering price, were also amply rewarded, though they could have done better on average by sticking their money in a Standard & Poor's 500 SPX, -0.07% index fund.
