Deletion of Wave strategy

Comment: Bookshops have literally hundreds of books where someone has developed a new buzzword with suitable language to convince the gullible that this latest fashion is really important. The only way we have to distinguish between such buzzwords and |notable topics is to rely on |reliable sources. The topics in these two articles do not have such |secondary sources

Comment: There appear to be three closely-related topics: Market entry strategy, Sprinkler strategy, Wave strategy, and there are three users recommending "keep" (Special:Contributions/BredMiller|BredMiller, Special:Contributions/Chris008|Chris008, Special:Contributions/Raid008|Raid008) who edit mainly in these topics. There are ''many'' online financial publications, and since none have been cited to support the |notability of these terms I think the very incidental comments in the linked pdf and munich-business-school.de link are not sufficient to keep these articles
