when a company is preparing itself for an ipo its executives and investment banking partners will take the company on a so called roadshow touring several institutional investors in an attempt to promote excitement for the new issue in some cases such as when the company is viewed as a leader or disruptor in an exciting new industry these roadshows occasionally succeed in producing widespread interest in the new ipo 
typically investors interested in a hot issue will be split into two basic camps in the first group are those who genuinely believe in the company s long term potential and wish to buy in on the ground floor on the other hand many investors are attracted to hot issues simply because they believe they can buy and then flip the shares for a short term gain this kind of speculative enthusiasm can sometimes produce bubble like conditions sometimes to the detriment of longer term investors in theory any kind of company could become a hot issue when undergoing an ipo in practice however this phenomenon is typically associated with high tech companies or those engaged in otherwise glamorous industry sectors established companies in mature industries tend not to attract the same level of investor enthusiasm perhaps because their business models are more stable and predictable than their hot issue peers real world example of a hot issuexyz corporation is a successful biotechnology startup that is preparing for its ipo with the help of its investment banking partners xyz successfully files form s 1 with the securities and exchange commission sec a necessary first step in the ipo process then it proceeds to meet with a wide variety of institutional investors in order to make the case for their company and justify a desired ipo valuation if xyz is successful in its investor presentations it could face a situation where its ipo is significantly oversubscribed in this situation its ipo would be seen as a hot issue with long term and speculative investors competing for the limited number of shares on offer although the actual price of the ipo is set after the market close on the ipo date the share price will often change significantly on the following day in the case of hot issues it is not uncommon for the share price to climb significantly sometimes by double digit percentages in a single day although it is by no means guaranteed this historical phenomenon has encouraged the tendency of speculators to bid up hot issue ipos in the hopes of securing a large short term gain
