What is Speculation: Definition and 34 Discussions

Speculation is the purchase of an asset (a commodity, goods, or real estate) with the hope that it will become more valuable in the near future. In finance, speculation is also the practice of engaging in risky financial transactions in an attempt to profit from short term fluctuations in the market value of a tradable financial instrument—rather than attempting to profit from the underlying financial attributes embodied in the instrument such as value addition, return on investment, or dividends.
Many speculators pay little attention to the fundamental value of a security and instead focus purely on price movements. Speculation can in principle involve any tradable good or financial instrument. Speculators are particularly common in the markets for stocks, bonds, commodity futures, currencies, fine art, collectibles, real estate, and derivatives.
Speculators play one of four primary roles in financial markets, along with hedgers, who engage in transactions to offset some other pre-existing risk, arbitrageurs who seek to profit from situations where fungible instruments trade at different prices in different market segments, and investors who seek profit through long-term ownership of an instrument's underlying attributes.

    Could there ever be a chromo-electric field weapon?

    In Star Trek, they mention a Chromo-electric pulse and Chromo-electric force field. I know chromo-electric fields hold the nuclear force together with gluons but could a highly advanced civilization use chromo-electric fields for weapons or protection?

    Is there a way to use the hydrogen in the human body?

    I recently read that there is enough hydrogen in the human body to lift 195 lbs off the ground. I know this sounds super-silly but if we ever develop nanites; could they manipulate the hydrogen and allow us to float?

    How big could a system of caverns be without collapsing?

    In the horror novel, the Descent, by Jeff Long, Earth has a system of deep caverns so extensive that they constitute a virtual "sub-planet," a kind of partial lower deck in the Earth's crust, whose mutated human inhabitants have horns and decorate their bodies with extensive scarification...

    B What are the potential alternatives to traditional teleportation and portals?

    Sorry, this might be a question you can only answer with speculation, but if anyone has any idea of how close we are to teleportation of inanimate objects or creating portals, I would love to know. I have always found teleportation and portals to be super cool. From what I've heard, in order...

    Can a Piston Engine Harvest Fusion Energy?

    Hi I have a really weird idea that is robbing me of my sleep. One of the many problems with fusion seems to be how to harvest the energy released by the reaction efficiently. So as I was slowly drifting into sleep I was wondering, how we usually harvest energy from reactions, and the piston...

    Speculation on the nature of collapsed stellar cores

    Neutron stars formed from supernova events are prohibited from becoming black holes because it is thought that the gravitational force is not enough to overcome Fermi degeneracy of the neutrons or quark gluon soup at the core of these objects, however, addition of more mass can overcome this...

    Black Hole Anti-Particle Speculation

    Electrons and protons have anti-particles. Has there ever been any speculation or work done on whether a black hole has an anti-particle such that if the two were to collide, they would annihilate each other? Probably not, but I was just curious.

    Sci-Fi: speculation about a desert planet

    I'm trying to cook up an interesting desert planet. Dune made me wonder if a tool-using species could turn a planet with plenty of water into a desert planet. Say, one nation starts hoarding water via the "catchments" we saw on Arakis (with some plausible mechanism to prevent evaporation)...

    Intelligent Life on Europa Speculation

    What is the impact of life on Earth and its environment?

    I am interested in black-holes because, even though I have no education to speak of and somebody here don't like me for it, I think differently about them. It is said there are 11 dimensions. Could it be that there have been 7 big bangs with the first one producing 4 dimensions and the next six...

    Speculation: Highest yield nuclear weapons in existance

    Since the cold war nuclear race we haven't really heard much about nuclear weapons development, but i imagine that the technology is pretty far ahead today compared to what it was when they detonated Tsar Bomba in 1961, which was a 50 mt. hydrogen bomb with a design that allowed 100 mt. So i...

    How Could the Proton and Neutron Fit into Electron Cavitation Speculation?

    Neither a theory nor a hypothesis, this is a kind of fun speculation toy I like to think about one in a while: In a book on mysticism I read a few years ago (written in the 1800s) the author asserted that atoms were cavitations in the aether. I think the phenomenon of cavitations in water...
