Because Bullfrog Spas are built completely differently, they utilize about 90% less plumbing than conventional hot tubs. Less plumbing equals less friction and less energy used to get water to the jets. In addition, most of the water delivery system in a Bullfrog Spa is inside of the proprietary H2Air Manifold on the JetPak and is submerged in the hot water. Any heat from water in the JetPak manifold transfers directly to the spa water rather than being lost to the cold outside environment. This unique and patented energy-saving feature will keep monthly power bills surprisingly low and will keep you relaxed and worry free!
In semi-strong-form efficiency, it is implied that share prices adjust to publicly available new information very rapidly and in an unbiased fashion, such that no excess returns can be earned by trading on that information. Semi-strong-form efficiency implies that neither fundamental analysis nor technical analysis techniques will be able to reliably produce excess returns. To test for semi-strong-form efficiency, the adjustments to previously unknown news must be of a reasonable size and must be instantaneous. To test for this, consistent upward or downward adjustments after the initial change must be looked for. If there are any such adjustments it would suggest that investors had interpreted the information in a biased fashion and hence in an inefficient manner.
